` fitted to them.-

It also' consists injthereniployment, in, the passage between such cylinders, of `a series of rollers between -whichthe soap is .caused to pass on its way from one cylinderl to another, and which `arecaused` to rotate ,-bythefrictibn and adhesion of the soap` passing be-A tween' them, Iandare thereby` caused to facilitate, expedite, and render more perfect the mixing pro- It further consists in the combination yof a reciprocating cutter `with a die or?` 'tube arranged in or at the mouth of a passagethrough which the'soap is forced from a cylinder by means of a piston in the shape of abar of the same trausverse'sect'ionalfoiym as the die, whereby the saidbar, as it issues from the die, 'is cut into cakes which are delivered upon an endless `apron or other carryingdeyice,`by' which the said cakes are removed.

"Figure 2 is afront viewof the cakc-making ap-y paratus. l Y f -`Similar letters'of reference indicatecorresponding parts in both tigures.- v fA Aare two upright cylinders, having air-tight `bottoms and loose lids or" covers, and fitted with airtight pistons, Bv B,'and having their pistons connected l `by rods, O C', with a'. lever `or beam, D, which works on `a shaft or gudgeon, E, supported intwo standards, F,'in such position that the connections of the rods with the lever or beam` are ori-opposite' sides of the said shaft or' from. l, 'lhe said lever or beam is extended beyond one of the rods, and its so-extended end is connected, by a gudgeon,and Vat equal distances there'- rod, G, -with a crank, H,`on a shaft, I, which 4is sup# portedin bearings'in standards, J J, and which has a slow rotary motion imparted to it by any suitable l means. i

"Between thelower parts of the two cylinders there I is a passage, K, of square `or other form, in which there is arranged, in'` the form of, a grating, aseries i of stationary knives, c a, fig. 1, which are Vset 'edge- There isalso arranged in the said passage a series of rollers,f1),'b,iig. 1, the axes of which are in a plane transverse to the passage,'and the journals or axes of which'are supported in suitable bearings in or close to the sides of the passage. These rollers are free to be'turned. by any substance passing between them. l

The passage K is furnishedj with a .sliding shutter, (l, by which communication between the cylinders may be closed..

To the side of the cylinder A furthest from the cyl inder A, near the bottoni thereof', there is attached a `horizontal tube,gL, whichis fitted, at isconnection with the cylinder, with a sliding gate,M, and the mouth of Ywhich may have the stareshape shownin fig. 2, or any other shape which it is desired to give to the cakes of soap to be produced.

Outside of the'mouth of this`pipe, which formsv a die, there is arranged,in vertical guides, e e, a sliding cutter-frame, f, which is furnished with alwire or other cutterg. 1

v'.lhecuttebframe is connected by a rod, h, with a crank, 'dion a shaft, j, which is supported in suitable bearings, It 7c, and which hasa very rapid rotary mo- .tion imparted.- to it by any suitable means, for the purpose of producing a reciprocating movement of the j cutter-frame and'cutter.

Under the mouth of the pipe and cutter, and extending some distance forward in front of them, is an endless apron, l, whose'upper surface moves outward from under the tube and cutter. l During the operation of mixing the soap the cutter` shaftj is thrown out of gear, the gate M is closed, andV the gate d open.

' This operation is performed in the following manner i .l

The covers are first takenl oli"` the cylinders and the pistons removed, and soap in a cold state is placed in l the cylinder, soap of one color in one, and Asoap Aof vanother color in the other, when soaps of diii'erent colors are'to be mixed. `'lfheV pistons and covers are then replaced, and the pistons are Set in operation by motion impartedlto the lever D from the crank H, each piston being,'in turn, depressed while the other is raised.- By this means the lsoapis forced .backward and forward from one cylinder to the other through the passage K, and between .the knives c a and rollers b b, and thereby thoroughly mixed, the rollers being caused to rotate by the adhesion and friction of the soap passing between them, and thereby being madeto'a'ssist very greatly in effecting the mixture.

When the miXture has Vbeen sufficiently effected, and while the piston BI Vis depressed, and that, B', raised, the shutter d is closed, the gate M opened, and the cutter g set inoperation, and, as the descent of vthe piston A causes the s oap to issue through the wise with the saidpassage. l

tube L in the shape of a bar, the transverse section of which corresponds with the form of the cakes to be produced, the cutter cuts it up into cakes, which full on and are carried olf by the endless apron l, whence they are removed by hand or otherwise.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The process of mixing soaps by means of pistons and cylinders with communicating passages, substantially as herein described.

2. The rollers b b, arranged and operating substantially as herein described, in the passage K between the cylinders.

3.' The reciprocating cutter g, 'in combination with the tube L, cylinder A':-ind piston B', substantially as and for the purpose herein specified.
